“…Those that answered, "very underweight", "slightly underweight", and "about the right weight" were considered to not perceive their weight as "overweight. " Participants that answered, "slightly overweight" and "very overweight" were considered to perceive their weight as "overweight", in line with other weight perception literature which compares those who perceive their weight as "overweight" versus those who do not perceive their weight as "overweight" [8,24,25].…”

Background The current study examined whether weight perception or age moderated associations between time spent on image-based social media and weight bias internalization (WBI). Methods Data come from the baseline visit of the Tracking Our Lives Study, a randomized control trial of college women (n = 200). Participants completed questionnaires assessing time spent on social media (continuous, overall and individual platforms Instagram, Facebook, and Snapchat), WBI (continuous), weight perception (perceive their weight as “overweight” vs. do not perceive their weight as “overweight”), age (continuous, 18–49 years), and confounders (race/ethnicity, parent education, sexual orientation, and BMI). Adjusted zero-inflated Poisson regressions were performed to determine if weight perception and age moderated associations between time spent on image-based social media and WBI. Results As expected, we found a positive association between overall time spent on image-based social media and WBI (β = 0.826, p < 0.001). In moderation analyses, the strength of the association was weakened among women who perceived their weight as “overweight” (β=-0.018, p = 0.006). Associations also weakened with age (β=-0.001, p < 0.001). The association between time spent on Instagram and WBI was also weakened with age (β=-0.014, p = 0.018), which was the only significant moderation found for individual social media platforms. Conclusions Our results suggest that image-based social media use is more strongly associated with increases in WBI among younger women.

“…Among girls and women, body mass indices (BMI) tend to increase from age 5 through adulthood, until around age 75 (Attard et al, 2013;Belsky et al, 2012;Song et al, 2018;Warrington et al, 2015;Yang et al, 2021), moving bodies further and further away from culturally prescribed thin body ideals. In girls, puberty is a time when these changes are particularly pronounced, and body changes during puberty have been prospectively associated with increases in body dissatisfaction, disordered eating behaviors, and eating disorder prevalence (Halvarsson et al, 2002;Klump et al, 2007), particularly in those who perceive themselves as overweight (Ackard & Peterson, 2001;Hahn et al, 2023).…”

“…Although children can generally accurately estimate their body size by approximately age 5 (Williamson & Delin, 2001), distortions in perceptions of body size (i.e., under-or over-estimation) are apparent in a substantial proportion of children, adolescents, and adults (Duncan et al, 2011;Stapleton et al, 2016;Steinsbekk et al, 2017). Perceiving oneself as "overweight" prior to puberty or in late adolescence is a stronger predictor of disordered eating behavior than objective body size (Ackard & Peterson, 2001;Hahn et al, 2023;Kim et al, 2008). Similarly, girls have exhibited greater levels of body dissatisfaction when they perceive their bodies as larger, regardless of their actual body size (Dion et al, 2016).…”

Background: Little is known regarding how disordered eating (DE) relates to perceived actual body size, ideal body size, and their discrepancy. This study examined changes in perceived actual body size, ideal body size, and actual-ideal discrepancies over time, and their relationship with subsequent DE. Methods: Participants were 759 female twins from the Minnesota Twin Family Study who reported on body image and DE every three to five years between approximately ages 11 to 29. We used multilevel modeling to examine developmental trajectories of body mass index (BMI) and Body Rating Scale Actual, Ideal, and Actual-Ideal discrepancy scores and compared the degree to which BMI, BRS body size perceptions, and body dissatisfaction predicted DE behaviors and attitudes over time. Participants were treated as singletons in analyses. Results: Perceived Actual body sizes and BMIs increased from age 10 to 33, whereas Ideal body sizes remained largely stable across time, resulting in growing Actual-Ideal discrepancies. Body size perceptions and Actual–Ideal discrepancies predicted subsequent DE behaviors and attitudes more strongly than did body dissatisfaction as measured by self-report questionnaires. Conclusions: This research advances understanding of how female body size perceptions and ideals change across development and highlights their relationship with subsequent DE.
